1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 9 C -76 A BALANCED RUTILE-AMPHOTERIC OXIDE FLUX COATED MMA ELECTRODE DEPOSITING A NICKEL BASED ALLOY HIGH IN BOTH CHROMIUM DATA SHEET NO. 141 SPECIFICATION AWS A5.13 CLASSIFICATION ENiCrMo-5 (nearest) PRODUCT DESCRIPTION The metallurgically engineered chemically neutral flux containing the major alloying elements is extruded onto a pure nickel core wire. The blend of silicates used during electrode production ensures both coating strength and resistance to subsequent moisture absorption. Metal recovery is some 150% with respect to weight of the core wire. WELDING FEATURES OF THE ELECTRODE Suitable for use on both AC and DC. Welds with a very stable, directional but low penetrating arc. Weld beads are exceptionally smooth and evenly rippled. Slag is normally self detaching and fillet welds slightly concave. The slag is fairly fluid allowing full control of run-out length and the smaller diameters are suited for positional welding. APPLICATIONS AND MATERIALS TO BE WELDED Extensively used to surface dies used in the drop forging industry when a combination of resistance to oxidation at elevated temperature is needed combined with thermal stability. Good initial hardness and the ability to work harden. It is of particular value when such dies need to be precision machined and extra ductility is needed at elevated temperature.
